abstract architectural maquette 3d model

Ultra clean 3D architectural structure on a stylized low-poly mountain base. A long rectangular concrete wall building placed on top of a faceted, angular, low-poly rock platform. The base terrain consists of sharp triangular geometric rock formations, folded surfaces, and crystalline pyramid-like shapes. Hard edges. No smooth organic terrain. Dark blue-gray matte material. On top sits a minimalistic elongated concrete wall structure with vertical panel segments and subtle industrial detailing. Brutalist architecture style. Flat roof with slight gravel texture. Long horizontal proportions. Studio lighting. Black background. High contrast. Sharp shadows. No environment. No sky. No vegetation. No realism. Style: abstract architectural maquette model. Materials: matte concrete, matte dark geometric rock. Clean topology. Game-ready mesh. High detail geometry. No textures baked from photos.
